[imp] Can't send over SMTP

[Aleksandar Lazic]

Dear List members,

I use the Horde 5.0.0beta6 and Imp H5 (6.0.0beta4). When I send mails I 
get the following error message

###
2012-10-25T01:51:44+02:00 ERR: HORDE [imp] Failed to add recipient: 
al-test at none.at
[SMTP: Invalid response code received from server (code: 504, response: 
5.5.2 <localhost>:
Helo command rejected: need fully-qualified hostname)
###

my config looks like http://pastebin.com/ueisu0ir
the versions of Horde are this http://pastebin.com/J8XdrimW

I can read mails over imap but can't send over smtp

I have also seen that in the Net_SMTP the variable localhost have the 
value localhost
and not the $conf['imap']['smtp']['localhost'] from the 
backends.local.php or backends.php

I have also created a ticket
http://bugs.horde.org/ticket/11572
and started to chat in irc.

I hope that I get a answer on any communication way.

thanks for any hint

Best regards
Aleks
